FLUE-STOPPER.

SPECIFICATION formingrpart of Letters Patent N0.V605,128, dated J' une7, 1898. Application filed January 20, 1898. Serial No. 667,325. (Nomodel.)

useful Improvements in Fine-Stoppers; and

I do declare the following to be a full, clear,

- and exact description of the invention, such formed upon the threadedend of the bolt atas will enable others skilled in the art to which itappertains to make and use the same.

My invention has relation to flue-Stoppers.

The object of the invention is to provide a device of this character bymeans Yof, which a dead-air chamber is formed in the flue-thimble,thereby preventing soot and ashes sifting out into the room at everylittle gust of wind, as Well as preventing the paper on the wallscorching around the thimble.

With this object in View the invention consists in certain features ofconstruction and combination of parts, which will be hereinaf-y terfully described and claimed.

In the accompanying drawings, Figure 1 iS alongitudinal sectional Viewthrough theuethimble and the flue-stopper, and Fig. 2 is a detailperspective view of the innersection of the stopper. l f

In said drawings, 1 denotes the flue-thimble, which may be of anysuitable or Wellknown construction.

The flue-stopper consists of the inner section A, the clamping-disk B,and the outer section C. Each of these parts has an'alined hole throughwhich passes a bolt D,lhaving at one end a head E and at the other end athread F.

A stop nut or shoulder is secured to or the front side of the'disk, anda clamping-nut is secured upon the bolt at the rear side of the innersection of the stopper and serves to clamp this Section of the stopperto the disk. The stopper'is expansible in order to enlarge or lessen itscircumference. In order to effect the ex'pansibility ofthe section ofthe stopper, I slit -it radially from vthe edge toward itscenter,`thereby forming separate and independent wings or sectors.

Thek cover is suitably dished, and is provided at its center with asquare seat to receive the clamping-nut above referred to.

The operation of the invention is as follows: When placed Within alue-thimble and it is desired to tighten the inner section of thestopper against the interior Wall of the flue to insure a tight fit, thehead of the bolt is turned,fwhich causes the disk B to be forced againstthe dished face of the inner section of the stopper, thereby spreadingor flattening it out and causing its edges to firmly engage Withtheinterior wall of the thimble.

Although I have specifically described the construction and relativearrangement lof the several elements of my invention, I do not desire tobe conined'to the same, as such changes' or modifications may be made asclearly fall within the scope of my invention Without departing from theSpirit thereof.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

A flue-stopper consisting of the inner and Aouter sections, the innerSection being dished and slit radially from its edge toward its center,a clamping-disk fitted to the dished side .of the'inner'section of thestopper, said sections and the clamping-disk provided with alinedopenings, .the -said inner section of .the stopper being provided on itsouter convex vface around its opening with a nut-seat, a
